Abstract:

The welded tank features fracture-tough steel and tube stiffeners to overcome problems evident in several failures of major tanks in recent years. Used extensively for grain storage in the Midwest, these tanks are subject to grain-induced meridional compressive forces. A new design features fracture-tough steel, elimination of built- discontinuities, and prevention of excessive tension-stress fields.
